Found by going back 2 or 3ish pages.
Explanation of why that is occurring is provided back there.
Thank you so much for your help, I've been stuck with this problem for weeks and it finally works.
I've been testing locally so far and everything works fine.
My version is v1.5.7d, the local PHP version is 7.4, and so is the server.
But whenever I move the site to the server, the plugin doesn't work at all except for loading images all the time when I input the quantity.
Any ideas?
Several come to mind, though not all specifically related to the plugin and in no particular order: files exist in the server that are not in the local version, file differences between the two, database differences that have some affect, two or more observers trying to monitor the same notifier but are loaded in a different sequence on the site than the local version, that there has been done html validation differences between the output, differences in jquery versions, etc.Quote:

Another mod that has fallen foul of changes made to the ZC 1.5.8 `shoppingCart` class which reassigned some variablesQuote:

The mod is going to require some reworking. Not sure who's managing this one now.
Have you tried using the beta version from GitHub? It can be found at https://github.com/Zen4All-nl/Zen-Ca...-Price-UpdaterQuote:
